Blow outs and tires
How many of you have had a blow out? I now carry two spares for my trailer. I've tried different tires and always have what the PSI is on the tire. Never had one go on any dirt roads always on the ...

Perhaps been in the trucking industry too long where the common factors for HD Tire blowouts and in all sizing from 16' thru 24.5 diameters there are Age of carcass(Most corporate accounts replace before five years), amount of Static Time(sitting in One Spot), excessive weight and improper inflation. There are numerous 15" LT tires but are harder to locate where capacities are not all that greater than ST series.
Time on a tire seems odd, but rubber compounds lose Elastomeric volatiles' over time, become harder over years as the natural solvents and softening agents leave. Hardened tires take side loading and impact pressures terribly.
Static Time where again the tire compounds are hardening also develop a memory on the flat spot at bottom, as the tire rolls, it heats and that 'flat spot' rounds out again yet is affecting cording buried within the tire that has also developed a position memory, in essence becomes a weak spot.
Tire rated "D" load is for Single position, cannot simply Double on one axle as side loading at near maximum weight will shift excessive weight to those outside tires in corners, short duration excess weight applications not so bad but repetitive and in other high stress as Severe Heat or Severe Cold can be disastrous on those tires reducing longevity before lose carcass strength. In Duals is where Two rated tire capacities can be nearly doubled.
Inflation above or below recommended for loading weight, many see Hard Tires and falsely believe reduction of pressure will soften impact loading, if the tires are of a harder initial compound or have age hardened lowering pressure will only add to sidewall flex and eventual heating within the carcass to point of fail. Opposite when airing Above rated pressures thinking can decrease slewing or side roll as tire heats from friction and environment temperature those pressures reach critical failure point.
Have installed six lug 16" wheels on my own trailers to accommodate heavier GVWR Tires on them yet axles retain the lower weight rating. Do not have a Toy Hauler as yet but looking and will be opting for heavier eight lug hub/axles for better options of tires.
